Simply record any message directly into the LITTLEmack communicator for one touch, single message playback up to two minutes in length. Connect a toy or battery-operated appliance for instant positive reinforcement. With its angled base and 2.5-in/6.4-cm activation surface, LITTLEmack is perfect for mounting and is recommended for persons who can access a smaller target area. Powered by a replaceable 9-volt battery, LITTLEmack never needs charging and can last for weeks or even months on a single battery.
